Starter issues on 1990 GMC Jimmy

It is actually a 1987. Does not want to start on first try. Cranks over, i was told something about a starter clutch, didnt realize that they are on cars too. Obviously gas and power is good, anyone got any ideas.
Thanks

If you mean that it does not want to crank over, then yes, it could be a starter problem, but make sure that the battery is ok and that the ignition switch works properly.
here is a 'No Start Diagnostic' sheet that we at RepairPal put together to help people with this issue and gives good instructions for inspecting a starter and /or battery problem.
